This is accomplished by placing the end" for combustion engines of the type in which of the pipe into the top of the can containing an oily vapor is drawn into the manifold of the lubricant, whereupon the suction applied the engine and distributed past the valves into from the engine through the pipe 7 will cause 5 the cylinders. The invention has for its printhe lubricant to be drawn from the can into 0 cipal objects the provision of a construction of p the container 1 until it reaches the desired level the kind specified having. improved means for therein, which level may be observed due to the insuring that the density or consistency of the fact that the container is of glass. The pipe, vapor supplied shall remain substantially 'contherefore, performs the dualfunction of an in- 10 stant regardless of changes of level in the re'serlet pipeand a filler or charging pipe. 651
